With triplet teenagers-and a house designed for adult tastes-Steve and Sue Campbell desperately need a casual outdoor room where their kids can have fun. Their current backyard moonlights as a gravel pit, but Dean and Derek have a rescue plan: they add a curving stone patio up against the house, put in a fire pit for marshmallow roasting, and add a putting green for entertainment. With lots of curving planting beds, plenty of grass, and some cool seating, Dean and Derek create an outdoor room perfect for the Campbell triplets... and all their teenage friends.
